Pharmaceutical purified water equipment is mostly used in pharmaceutical production lines in the pharmaceutical industry to meet the needs of water for pharmaceutical production liquids and cleaning of pharmaceutical raw materials
.
Understanding the factors affecting the quality of purified water equipment can help us effectively protect the quality of pharmaceutical purified water effluent and promote the safety of production water for
enterprises.
Pharmaceutical purified water equipment has three main stages in water production, pretreatment stage, reverse osmosis treatment stage, and distribution and transportation stage
.
Among them, the impact of the reverse osmosis treatment stage on water quality is crucial
.
So, what are the factors that affect the working performance of pharmaceutical purified water equipment at this stage? Fig.

Operating pressure: The water permeability of the membrane increases with the increase of the operating pressure within a certain range, and the desalination rate decreases with the decrease of the operating pressure; 2.
Water temperature: Changes in water temperature will cause changes in the viscosity coefficient of the solution, resulting in changes in water production; 3.
Salt content of raw water: If the salt content in raw water is high, the osmotic pressure will increase, and a higher operating pressure is required; 4.
Operation cycle: the increase of the operation cycle will affect the water production, in general, every three years the operation cycle will reduce the water production by 20% to 30%; 5.
Operation recovery rate: The level of salt content of concentrated water depends on the operation recovery rate, and within a certain range, the operation recovery rate is inversely proportional
to the water production.
It can be seen that the stable operation of pharmaceutical purified water equipment and the strict control of its inlet water quality standards are important factors for them to maintain a high-quality water production state, and doing a good job in its operation and maintenance and inlet water quality control can effectively provide pharmaceutical companies with continuous and stable supply of water sources
that meet the standards.
